Scope and Contents The microfilms were made before the papers had been organised, catalogued and assigned their present classmarks. As a result, the order of the records on the microfilms often differs from that found in the online catalogue. Consult the hard copy catalogues of these collections (available in the Manuscripts Reading Room) to obtain the classmark in use at the time of filming. RGO 3/15-29 were not filmed as they are fair and duplicate copies of items 1-14. RGO 3/46 was also not filmed as it was...
